Geometry

'hypotenuse', lit. 'stretching under'. It refers to how the hypotenuse "stretches under" the right angle. The word is Classical Greek in origin.

hypotenuse lit. 'stretching under'. It refers to how the hypotenuse "stretches under" the right angle. ( From Classical Greek).

It is the line opposite the right angle in a triangle.

The side opposite the right angle is called the hypotenuse.

The right angle (90 degree angle).

ANSWER

What measurement unit do you mean?

1 inch equals 25.4 millimeters or 2.54 centimeters or 0.0254 meters or 0.0000254 kilometers

The only number is 13 X 1 or 1 X 13... If your trying to get an equation to equal 13 you have to add up to get to 13.

Example- 9+4x1= 13

11 vertices (one more than the number of vertices in the base).

Multiply the 'feet' together to arrive at 'cubic feet'.

Then divide by '27', as there are 27 cu.ft = 1 cu.yd.,

Hence

120 ft X 40 dt x 1 ft = 480 cu.ft.

480 cu.ft. / 27 cu.ft. = 17.777... cu.yds. = 17 7/9 cu/yds

NB the .point seven' decimal recur to infinity, hence the mathematical notation of three or more dots after the last decimal.

A circle does NOT have CUBIC FEET. A circle has an AREA and a CIRCUMFERENCE.

A Sphere has CUBIC FEET. A sphere has a VOLUME, SURFACE AREA, and a CIRCUMFERENCE.

The eq'n for the volume of a sphere is

V(Sphere) = (4/3) pi r^(3)

Out of the figures quoted in your question, which is the radius(r)?

Use the eq'n

Int. Ang = 180 - ( 360/n sides).

Algebraically rearrange

360/n = 180 - INT. ANG.

n/360 = 1/[180 - INT. ANG]

n = 360/[180 - Int. ANG]

Substitute

n = 360/[180 - 176]

n = 360/4

n = 90 sides.

A polygon of eight sides is an OCTAGON.

INT/ Ang = 180 - ( 360/8)

INt. Ang. = (1440 - 360() / 8

INT. Ang = 1080/ 8

INT. Ang = 135 degrees.

First a nonagon is a 9 sided figure.

Ext. Angle = 360 / 9

EXT. Ang = 40 degrees.

Hence

Interior Angle = 180 - 40 = 140 degrees.

An angle that exceeds 180° but is less than 360° is called a reflex angle.

If you ask this, you fail

Octahedron

Use the equation

C = pi*d

Substitute

C = 3.14 * 25

C = 78.5 ft

NB This is only an approximate value, because '3.14' is only an approximate valuer for 'pi' , but convenient to use.

The other eq'n to use is

C = 2 pi r

Where 2r = d ( two radii equals one diameter ) . NB . 'radii' is the common noun plural of 'radius'. NOT 'radiuses'.

C = pi*d

The ratio is ALWAYS 'pi' for any circle, however, large or small.

pi is approximately 3.141592 , or 3.14, or 22/7

'pi' is an irrational number, which means the decimal digits go to infinity, AND the digits are NOT in any regular order.

To 'section' . However, if you mean two EQUAL parts, then it is 'BISECTION'.

To cut or divide into two parts., To divide into two equal parts.

It's called 'BISECTION'.

To determine if the sides 8, 13, and 26 can form a right triangle, we can apply the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) should equal the sum of the squares of the other two sides. Here, (26^2 = 676) and (8^2 + 13^2 = 64 + 169 = 233). Since (676 \neq 233), the sides 8, 13, and 26 do not form a right triangle.

C = 2 pi r

A = pi r^(2)

Hence

r = C /(2 pi)

Substitute

A = pi [C / (2pi)]^(2) or

Cancel down by 'pi'

A = C^(2)/ (4pi) ' Area in terms of circumference.

As many as you like.

However, being 'regular' all the sides must be of the same length.

The word ' poly' means 'MANY/.

As many as you like!!!!!

The prefix 'poly' means ' MANY.
